SEPARABLE FASTENER.

SPECIFICATION forming part of Letters Patent No. 624,896, dated May 16, 1899. Application filed February 15, 1898, Serial No. 670,384. (No model.)

To an whom it may concern:

Be itknown that I, GEORGE E. ADAMS, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Separable Fasteners; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to improvements in separable fasteners, such as are ordinarily used in uniting the overlapping edges of garments, gloves, supporters, and the like; and it has for its object to provide an improved construction whereby the attachment of the fastening to the garment, web, or the like is greatly simplified and at the same time rendered secure against accidental detachment.

Referring to the accompanying drawings, Figure 1 is a perspective view of one member of a detachable fastener constructed in accordance with my present invention applied to a piece of webbing. Fig. 2 is a similar view looking at the opposite side of the web. Fig. 3 is a vertical section through the same; and Fig. 4 is a corresponding section with the two parts detached, showing their shape before they are assembled. Fig. 5 is-a vertical section of a modification, showing the parts in reversed relation as compared with the construction illustrated in the first four figures.

Like letters of reference in the several figures indicate the same parts.

In said drawings the letter A, Figs. 1 to 4, indicates what for convenience I shall term the toppiece of the member of the separable fastener illustrated, and which member, it will be noted, is a socket member having a central aperture a, adapted for the reception of a stud member, (not illustrated,) but which may be of any ordinary or preferred construction.

Incarrying this invention into practice one of the pieces, preferably the top piece A, Figs. 1, 3, and 4, is provided with an outwardly-extending base portion A, terminating in an under and inwardly turned flange C, forming within the piece an annular recess 0, the top wall of which extends a greater distance toward the center of the piece than the bottom wall, said top wall thus forming an abutment against which the holding-points of the cooperating piece will be deflected outwardly and into the annular recess. This recess is only of sufficient width to permit the holding points to enter therein, as will be presently ex plained.

The cooperating piece Bis preferably made of sheet metal substantially circular in form and may have a central opening b, which may in some instances, as at b in Fig. 5, form the aperture for the reception of the stud memher. In addition this cooperating piece is provided with a series of peripheral points B which are normally set at a slight inclination, so as to readily penetrate the goods or webbing to which the fastener is to be applied and enter the open base A, Fig. 4, of the top piece, when if pressure is applied to the two pieces the said points will strike the top wall of the annular recess and be bent or spread outwardly into the said recess, from which they cannot be withdrawn by any ordinary strain applied to the fastener or goods to which it is secured.

The points or teeth 13 are preferably somewhat widely separated and are inclined at such an angle that they will readily spread outwardly when brought into contact with any flat surface, thereby avoiding the necessity of employing a special anvil or other'de vice for spreading them or directing them properly when the two parts are forced to gether. In the preferred construction also when the two parts are assembled, asillustrated in Figs. 1,2, and 3, the piece/B is preferably forced up until its points or prongs and inner part or body portion are approxi mately in or close to the same plane, thereby materially reducing-the thickness of the fas= t'ener and rendering the attachment to the fabric or webbing much more secure. In effect the body of the bottom piece is forced up into the base of the top piece, as will be readily understood from Fig. 3. When, however,

it is desired that the aperture for the reception of the stud member should be in the piece having the prongs at its edges, such piece is preferably made crowning, as illustrated in Fig. 5 at B B so as to form a chamber within the fastener and an aperture 1) for the reception of the head of the stud mem- It will be noted that the diameter of the body portion of the piece having the prongs on its periphery is less than the opening through which the prongs enter the cooperating section. Thus the edge of the body portion of the said piece may enter the cooperating section and when the prongs are straightened out will be held in position with the fabric between the two sections.

With the fastener thus described no special appliances are necessary in securing it to the garment or webbing and it is especially Well adapted for use upon tapes, &c., which are to be subsequently sewed upon childrens garments, although I do not wish to be limited to any particular use of the device.

It will be particularly noted, first, that the recess for the points is just wide enough to admit the points, the edge of the recess holding the fabric back and causing the points to penetrate the same, and thus the size of the device may be reduced sufficiently to make it practical for use as a glove or garment fastener of ordinary dimensions, and, secondly, that the points are sharpened to penetrate through the goods,and the recess in the top piece is only of a width to admitsaid points and exclude or hold back the fabric or goods through which the points pass. In other words, the points themselves substantially fill the recess transversely, or so nearly fill it as to prevent the goods from being carried into the recess by the points; and so any material folding of the goods around the device is obviated and at the same time great strength of attachment is secured and the device is made of a minimum thickness.

I claim- 1. The herein-described member fora separable fastener comprising two pieces, one havin g a peripheral inwardly-turned flange forming a narrow annular internal recess with an entrance-opening for the body of the other piece, and the other piece having a circular body portion of less diameter than the diameter of said opening and a series of peripheral sharp penetrating and holding points or pro jections lying in substantially the plane of the edge of the body portion and projecting through the goods and under the inwardlyturned portion of the flange on the opposite section to unite the two sections, whereby the thickness of the device is reduced and the folding of the goods around the fastener is prevented.

2. The herein-described member for separable fasteners comprising the top piece having the outwardly-extending base and peripheral inwardly-turned flange forming the narrow internal recess and the cooperating piece having the substantially circular body portion formed of sheet metal and having the series of separated and sharpened peripheral holding-points seating in the annular recess in the top piece and of a thickness to themselves substantially fill the same, the body portion of the bottom section being of less diameter than the opening in the bottom of the top section; substantially as described.

GEORGE E. ADAMS.
